test_policy assumes oslo.policy internal implementationd details

[Tim Hinrichs]

Congress's test_policy assumes that oslo.policy uses urlrequest.urlopen(), just like Neutron used to do. The mitaka release changes those internals and hence our tests fail.

Here's the same bug filed for Neutron.

    Change devstack to OS_PROJECT_NAME and avoid mocking oslo.policy internals

    To pass the tests in gate, this commit has 2 separate changes

    1) OS_TENANT_NAME is no longer used in the latest devstack, it causes all
    datasource driver fail, as well as jenkins gate failure.

    This fix changes devstack to use OS_PROJECT_NAME

    2) Previously, we tested oslo.policy by mocking out one of the internals
    of oslo.policy, just like Neutron. Besides being improper, the newest
    release of oslo.policy broke that test, which is what is blocking
    the tip of master currently.

    This fix shamelessly copies the fix out of Neutron, mocking out
    at the layer of HTTPCheck.
